ing openingsin which are pivot shafts 5 and 6 to which are fixed upper and lower lever orhaininer members 7 and S. The upper hammer member 7 is actuated by a cam lever 9, engaging a cam. groove on one side of the cam 10 fixed on shaft 1-, while the hammer 8 is actuated by a similar cam lever 11 actuated from a cam groove on the other face of the cam 10. wardly inclined and forwardly projecting feed frame pivoted on an inclined axis, the bearings therefor'being shown at 13 and 14- in Fig. 1. The forward end of the frame 12carries, in aligned perforations therein, a pair of telescopically related punch. and set mechanisms shown generally at 15 and 16, these mechanisms cooperating with a central anvil member 17 carried by a support 18 fixed at its rear end to the frame 12. This anvil member has setting surf-aces thereon to cooperate with the oppositely disposed sets in a manner well understood in the art. Leaf springs 19 and 20, pivoted at 21 and 22 to the hammer elements '7 and 8, engage heads 23 and 24 of the punch and set mechanisms to retain the same normally in contact with the hammers by the rocking of which the punches and sets are caused to move toward the anvil element in proper time relation to punch the material and set eyelets therein. One side of the frame 12, as shown in Fig. 2, isprovided with a pair of ears 25 and 26 between which is pivoted one end of a link 27. This link is pivoted at its other end 28 to a block adjustably fitted in a groove in a lever 29 pivoted in any suitable manner to the machine frame. The lever 29 carries a depending cam follower 30 which rides in a groove 31 in an edge cam 32 fixed to the shaft 1. The parts above described are substantially as shown in the Eames and Jacques Patent 1,971,688, granted November 7, 1922, and operate in subofthis type is already well known in the art and hence no detail description thereof is deemed necessary in this application, as it forms no oart of this invention. 7 i

At 39 is shown a spiral gear operatively connected to the mechanism within the hopper 35, and at 40 18. shown a mating spiral At 12 is shown a down gear carried by a shaft 41. Shaft 11 is journaled in a bracket l2 fixed to the bracket '3, and carries at its outer end a friction wheel 120 which may be inoved into contact with a mating wheel l3 carried on the shaft 4. At 44 is indicated a driving pulley over which passes a power belt 45, and at 4-6 is shown the usual handwheel. The pulley 44: is connected to the shaft 4 by means of a stop mechanism herein shown as of the type more fully described and claimed in the application of G. N. Jacques, S01. No. 392,200, filed June 28, 1920, the details of which are not herein described, as this mechanism forms no part of the present invention, 2

in Figs. 7 and 8, is shown a slightly modified construction relating primarly to the mounting of the hopper and related parts. In this construction a bracket 42*, corespending to the bracket 12 shown in Fig. 2, carries an extension 4-21 which supports a hopper 350 having eyelet distributing mechanism actuated through the spiral gear 390, corresponding to the gear 39 shown in Fig. 2. This construction eliminates the arm shown in Fig. 2. A supporting bracket 370 carries the eyelet reservoir 380 in a similar manner to the bracket 37 of the first form, this construction, however, considerably modifying the upper end of the bracket 200 corresponding to the bracket 2 of the other form. In this form a considerable shortening of the machine has been effected by a closer positioning of the actuating cams shown in Fig. 7 at 10 and 320. In all other respects the parts are the same as before described.

Referring more particularly to Figs. 1 and 3, the inner end of the shaft 4 termi- ,nates in a crank pin which carries the follower 51. This follower and a rod form an articulated pitman or connecting-rod for operating the raceway and the presserfoot, and are connected to each other by a pivot member 5%. The rod 55 being embraced by a pair of ears 52 and 53 formed on the fol lower totake the pivot-member. This articulated construction provides for universal angular movement of the rod At its forward end rod has a threaded poi-fora tion for the reception of a threaded shank 56 carriedby a'ball 57, a lock nut 58 retaining the shank in adjusted position lengthwise of the rod At 59 is shown a block which couples and spaces the delivery ends the shank 56 which may be engaged by n th. raceway is pivoted the all 361 for screw driver passed through the sleeve 61, mov ment o ii and by which it may be turned to adjust the this pimt being shank 56 lengthwise of the rod The lot feed. so us to 3 5 sleeve 61 ins a 1 air of notches diametrically some in )OS; 7

sleeve 93 pivotedat 94 to the upper hammer element 7.

Referring now to figs. 3 and 9, each raceway element of the raceway has a forwardly extended open end 100 from which the eyelets may be, picked by the corresponding punch in a manner \JQlllllitiQE- stood in the art.- In order to prevent the eyelets from passing freely fromjthe raceway ends, a lever member 101 is pivoted at 102 to eachraceway, andhas aforwardly extending finger portion 103 which no: mally projects partially in front of the opening 100 to obstruct the same. 10% is shown a rearwardly :rtcn ing portion of the lever having a slot thro gh which passes a stud 105 threaded at inner end into the raceway, and having threaded on other end a polygonal nut 1053. The portion 104 carries ancutwardly extending lug 106 adapted to closely contact with the side osition shown of the nut 105, and in the p 3 1n F1 9 erevents the lata i l V a turned. A COll spring llit, bolt 105, bears between the raceway ant. end 10% of the lever and normally re the same in the POSlt'lOil shown in j. with the finger 103 obstructing thepass'a of eyelets. it is evident that an eyelet can be forcibly removed from the opennu against the force of the spri 10! i allows the finger 103 (Of/mid, 1nd that by turningthe nut 1.05 the degree of obstruction offered by the finger 103 le regulated. The lug 10G normally prevents such turning of the nut 105, but by depression of the end 104; of the lever, this lug is re tracted from contact with the nut whereupon it may be turned, this position of the lever, however, being abnormal and not reached in the normal operation of the machine when the eyelets are forcibly removed from the raceway ends. V

The operation of the above described mechanism is as follows: 'lwo pieces of material are placed in snnerposed relation between the presser foot and work supporcciements 79 and 6%), and

c are brought into-position one on either side of the anvil 1?, The parts are now in the relative posit1ons shown 11]. Fig. 4;. l hen the machine is put into operation, the ham Iner elements 7 and 8 force the punch and set elements toward the anvil to punch the work. In this position of the parts the raccways support the two leading eyelets in register with the punches which pa through said eyelets. In the further operation of the machine the raceway is'drawn rearwardly by crank away from the punches, which pull the threaded eyelets from the raceway, the fingers 103 yieldi to release the eyelets. Further movement. of the punches causes the punching of the material, and the crank 50, acting on the lever 86, rocks the same about the roller S-l and moves it bodily to the rear so that the lever acts on the roll to lift the presscr foot from the work, the position of these parts being then as shown in Fig. 5. While the punches are in engagement with he work,cani32,actuating the feed mechanism, swings the feed frame to the left as shown in Fig. 2, or in the direction of the arrow on Fig. 5. fit or near the end of the feed motion the hammer elements 7 and c actuate the sets to set the eyelets, already threaded on thepunches, whereupon the hammer elements retractthe punches and sets from the material. is this action is taking place, crank 50 moves the lever 86 forwardly, al-

lowing the presser foot to again engage the material, the parts being then as shown in Fig. The feed frame then begins its return. motion preparatory to a succeeding punching operation at which time also the raceway has again been moved by crank. 55-0 toplace the new leading eyelets in register vith the punches.

it is to'be understood that the pressure of the presser foot on the work is relieved pr 1 (O and during the feeding period to avoid coimter-drag, and also that the confronting work elements are held in contact in advance of the punching and setting localities during the entire action of the machine, and clamned by the presser foot while the feed frame is returning, at which time the punches and sets are out of engagement with the work.

il lvillg thus described certain embodiments of this invention it should be recognized that various modifications and changes might be made therein without departing from its spirit or scope as defined by the appended claims.
